SPECIFICATION forming part of Letters Patent No. 451,493, dated May 5, 1891.

A Application filed May 26, 1890. Serial No. 353,132. (No model.)

To all whom it may concern: anism not being shown,) all of these rods be- Be it known that I, TILLIAM G. LATIMER, ing supported in suitable guides E. The rods a citizen of the United States, residing at De D are preferably round, and to prevent their troit, in the county of WVayne and State of turning on their axis a guide-arm a is at- 5 Michigan, have invented certaiirnew and usetached to their front side, projecting between ful Improvements in Gash-Registers, of which the register-actuating rods and guided therethe following is a specification, reference beby, the register-actuating rods being secured ing had therein to the accompanying drawat the side of the key-levers, while the indiings. cater-rods rest centrally upon the key-levers. IO This invention relates to new and useful lheindicator-rods at theirupper endscarry improvements in indicating mechanism for the rearwardly-projecting pins 1), adapted to cash-registers; and the invention consists in bear against the disk-levers, of which there the peculiar construction of such mechanism, are three 0 0 0 one for each group.

These levers each carry struction, arrangement, and combination of a segmental rack-bar (Z d (P.

The machine belongs the casing, the disk-levers so constructed as to that class in which theindication is effected to be differently moved by each indicatorby arranging two or more banks or groups rod. This I preferably accomplish by formof nine keys, the keys of each group being ing a series of bearings 9 upon the lower side numbered from 1 to 9, respectively. Each of the lever, each bearing being arranged in S5 5 group represents a monetary denomination, such relation to the pins 1) upon the indiunits, tens, and hundreds.

The same result may be of the indication.

it; are pins, one upon the rear side of each of the in icator-rods and adapted to rest upon the top of the bar It in their elevated position.

Z is a cross-bar extending across all the keys of the machine and supported by means of the hanger m. This bar carries the vertical supporting-rods n, upon which is pivotally secured the striker-arm 0, adapted to move the bar p horizontally, said bar being held in position by means of the links q q. The link g has the upwardly extended arm 0-, which strikes the arm a", connected to the bar it to turn the bar upon its pivot in such a manner as to disengage it from the pin 7.: and allow the operated tablet-rod to drop.

The parts being thus constructed, their operation is as follows: The disks being in their normal position with all of the ciphers exposed, should the operator desire to indicate $7.60, (the amount shown in Fig. 4,) he does so by depressing the 6-key in the tens group, carrying up its indicator-rod. The first move ment of the key will withdraw the bar it from the rear side of the indicator-rods through the mechanism. described, which will allow any previously-operated keys tov drop. As soon as the striker-arm 0 has passed the bar 1) said bar will return to its normal position by gravity, allowing the bar it to again assume its normal position. (Shown in Fig. 3.) In the continued upward movement of the indicatorrod the pin 7t will turn the bar 77, upon its pivot until the pin has passed, when the bar willdrop back again and prevent the descent of theindicator-rod. In the upward movement of the pin 1) upon the indicator-rod it will strike its bearing upon the disk-levers, raising said levers until the key has finished its stroke, rotating the disk through the medium of the rack-bar d until the 6 is exposed to view. Upon releasing the key the key-lever will return to its normal position, but the rod will remain in its elevated position by the pin resting upon the bar It. The 7-key having been simultaneously struck, italso will be held up (the dollars-disk having been rotated in the manner described) until the 7 is exposed through the aperture. IVith this number exposed,it having been also registered by any suitable registering mechanism, if the operator next desired to indicate a one-dollar sale he would strike the l in the dollar group. The lever 0 will be held up by the 7-indioator rod previously struck until it is released by the withdrawal of the bar it, when it will fall by gravity and bear upon the rising pin Z) of the rod operated by the l-key, the old indication being effaced and the new indication being effected in the manner described. It will thus be seen that by having a single flat disk for each group I am enabled to effect the indication in a most simple manner and with very simple mechanism. By this construction it will be seen that the operating-lever and the indicatingdisk are both moved proportionate to the value of the key struck. It will also be seen that if two keys are simultaneously struck only the figure representing the key of highest value will be exposed to view. Thus all necessity of having mechanism to prevent the simultaneous operation of two keys is obviated. The disk is rotated toward normal by the weight of the operating mechanism bringing down the operating lever and through the medium of the segmental gear and the geanwheel.

I claim- 7 1. In a cash-register, the combination, with the frame, of three disks having digits thereon mounted in the frame, two in line and one in the rear and between the others, gears on said disks, levers having segmental racks thereon engaging with the gears and stepped lower edges, and a series of operating-keys arranged to engage the stepped portion of the levers, substantially as described.

2. In a cash-register, the combination, with a series of rotary disks having digits on their faces, of a series of stepped levers having racks thereon, gears connected with the disks engaging the racks, and keys for actuating the levers, substantially as described.

3. Ina cash-indicator,the co1nbination,with a series of rotary disks having digits thereon, of gears on the shafts of the disks, two levers fulcrumed on a common shaft and formed with segmental racks for engaging the gears on the disks, and a lever fulcrnmed at a point remote from the other fulcrum and having a segmental gear engaging the gear on a disk, the inner edge of the lever being formed with a series of strips and keys for engaging with the lovers, substantially as described.

4:. In a cash-indicator, the combination, with the frame, of a series of disks having digit signs on their front faces, a series of lovers having stepped lower edges and segmental racks, gears on the disks, indicating-rods, horizontal pins on the upper ends of the rods, and keys for moving the rods, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
